This invention aims to provide a simple means whereby a signal will be sounde-d in the event of conflagrat-ion, the structure being capable of being mounted onthe ceiling of a basement, in chimneys, or any .1 other place where a fire is likely to start unobserved.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that sort to which thepresw cut invention appertains.

With the above and other objects in view, which will appear as ceeds, the invention resides in the combination and arrangement of parts and in the 15 details of constructionhereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed, within the scope of what is'claimed, withoutde- 2a parting from the spirit of the invention.

In the accompanying drawings: Figure 1 shows 1n elevation, a system constructed in accordance w th the invention; and I Figure 2 is a similar view showing a modification.

In carrying out the invention, as shown in Figure 1, there is provided a pair of guides 1 in which slides an operating member 2. The operating member 2 is depressedby a compression spring of the operating member, one end of the spring engaging one of the guides 1, and the opposite end of the spring engaging an abutment 4 on the operating member 2, the abutment being a washer and pin, if desired.

The numeral 5 designates a pair of guides in which a slide 6 is mounted for reciprocation, the slide 6 preferably being a rigid arm provided at one end with a rectangularly disposed support 7 engaged beneath the reduced lower end 8 of the operating member 2, to hold the operating me her against the thrust of the spring 8.

The numeral 9 marks a compression spring disposed about a portion of the slide 6. One end of the spring '9 abutsagainst one of the guides 5, and the other end of the spring engages an abutment 10 on the slide 6. The

J abutment 10 may conslst ofa pin and washer.

"by the numeral 14. The connection'may be the description pro"-v 8 of the operating member I erating member against movement responsive 'crumed intermediate its ends,

flexible connection unites one endof the led og, cooperating with the; teeth 21fofa wheel 0f the spring being connected to the stub, disposed about a fportion vof the operatmg member 2, the operating member mov ng downwardly. 111 Flgure 1,

The numeral 11 marks any accessible 'part of a buildi'ng, carrying an anchor 12, such as a 1 screweye.

A. connection extends between the anchor 12and the slide 6, and is denoted generally made in various ways, but as'shownpit com} prises links 15' provided with rings 16] at their ends, fusible wires 17 being connectedv between the rings 16,.and'between one of the rings 16 and the anchor 12. The connection 14;, of, course, maybe of'any. desired length:

its function is to hold the' slide ;6 drawn to the left, as shown in Figure, 1 the :spring 9 being under compression, andthe support 7- of the slide 6 being disposed beneath the end 2,to' hold the op- -to the spring 3. I p H I Thenumeral 18 marks a leverwhich is'fulas at 19; A

ver '18 withone end'of'the operating mem- -er 2. The lever 18 constitutes a'stopping' 2 2 to hold the wheel againstrotati'on, the wheel being journaled on the fixed stub shaft 23; Y The wheel 22 is rotated through the in;- strumentality of atorsionspring 2%,"one end ing moved out of engagementfwith the end 8 under the action of the spring 3, the lever or dog 18 being tilted by the action of the connection 20, and being disengaged from the teeth 21 of the wheel 22. The wheel22 thenrotates under the action of the spring 24:, and the teeth 21 cause the striker 25 to swing on its fulcrum 26, the hammer 27 hitting the gong which will be obtrusively audible.

In Figure 2, a modification-of the invention is shown. In Figure 2, parts herein before described have been designated by numerals previously used, with the suffix a. The numeral 29 designates an electric bell,

or similar audible signal, interposed in a circuit 30 in whichis located a source 31 of electrical energy. In the circuit 30 is located a switch mechanism 32, one member 83 of which is held open byrthe lever 18.

When the fusible wire 17 melts, the lever l8 -is swung to permit the switch member 33 to close, and then current will vfiow through the circuit 30 to energize and operate the signal 29.

lVe claim a 1. A signal-actuating device comprising a lever,'means for fulcruming the lever intermediate its ends, an operating member mounted for sliding movement, a connection between the operating member and one end ofthe lever, means for holding the operating member against movement toward signal-actuating position, a retracting spring cooperating with the last-specified means, and fusible mechanism restraining the lastspecified means against movement responsive to the retracting spring.

2. A signal-actuating device comprising two substantially like structures, one of said structures including a slide, and the other of said structures including an operating mem ber, the slide and the operating member having straight-line movement in directionssubstantially at .right angles to each other,

spring. means for moving the operating mem-- ber to signal-actuating position, the slide engagingthe operating member to hold the operating member against movement responsive to the spring means, spring means for moving the slide out of engagement with the operating member, and fusible means rcstraining the slide against movement, responsive to the last-specified spring means, to a position out of engagement with the operating member.

3. Av signal-actuating device comprising two substantially like structures, one of said structures including .a slide, and the other of-said structures including an operating member, the slide and the operating member havingstraight-line movement in directions substantially at right-angles to each other, the operating member being downwardly movable to signal-actuating position,

the slide supporting the operating member.

to hold the operatingimember against downward movement to signal-actuating position, yieldable means for moving the slide out of supporting relation with respect to the operatingmember, and fusible means restrain- 28, and producing a signal natures.
